For those of you who are possibly like me and not too creative when it comes to graphics for a very reasonable price BannersWorld.com will create a very nice advertising banner in less than 42hrs for you.
The copying if there is any is very minor and not even worth a post I think any way, maybe one inspired the other.
I used BannersMall.com for quite a few banners, it was an amazing service I found it refreshing to get such a service from a company that dealt in banners normally design companys do them as a side line these are the experts.
I would say they are the best out there for banners.
I recommend them to all my clients, there site is really nice too no wonder people are getting inspired by it.
